- Primary Role
- UNIX System Administrator
- Duties
-
- Member of a team varying from 12 to 16, supporting from 150 to 300 UNIX systems/LPARs, including AIX, Solaris, Tru64, Linux and SCO. Systems vary from Steelmaking production control systems to large (1+ TiB) SAP/Oracle AIX systems with an international user base.
- Typical tasks include installation, patching, security management, troubleshooting, backup and recovery, space management and performance tuning.
- Main support contact for two Solaris (now AIX) based TSM backup servers, with around 180 clients (UNIX, OpenVMS, WinNT and Macintosh).
- Providing rostered 24x7 on-call support.
- Primary unofficial backup for rostered on-call support personnel for any technical issues.
- Mentor for colleagues on most supported technologies.
- Australian Subject Matter Expert for Tru64 UNIX.
- Main contact for performance tuning of supported systems.
- Main contact for arcane network protocols, including managing a Tru64 system running as a DECnet Phase V to SNA LU6.2 gateway, and several Tru64 systems using the PLC communications protocols GCOM.
- Main contact for the management of a MediaWiki based team documentation archive.
- Achievements
-
- Dec 2006: Successfully migrated and upgraded a TSM server from TSM 5.1.4.6, Solaris 2.7 running on a Sun E3500 with A5100 storage, to TSM 5.3.3.4, AIX 5.3 running on a p520 with HDS SAN attached storage. TSM database unload was approximately 30 GiB, and the upgrade, including auditdb, was completed in approximately 24 hours.
- Feb 2006: Involved in commissioning a number of US-based p570 based LPARs, including configuring redundant Virtual I/O Servers providing both disk and network.
- May 2005: Involved in a second major project for the same client configuring a further 42 p570 LPARs, and the migration of Oracle databases, live, over the network, using a customized rsync, between the US and Australia, minimizing outage time for cut-over. Some of the migrated databases were slightly less than 1 terabyte in size, and database outage duration for cut-over was less than 30 minutes. Mentored two new graduates with 2 months experience to handle much of the physical cabling, LPARing, installation, and some migration tasks.
- Jan 2005: Involved in a technical role in a major project for the configuring of approximately 12 p570 LPARs for the running of SAP+Oracle for a large client. Data and applications were successfully migrated from existing SP infrastructure.
- Jul 2003: Mentor and senior technical specialist assisting with the migration of a MIMS/Oracle application from a heavily customized and scripted Tru64 environment to new AIX POWER4 hardware.
- 2000: Technical resource involved in the separation of DNS, SMTP, and other network services with the splitting of one company into two separate companies and network entities.
